UNITED STATES HARRY N. DICKSON, OF ORLANDO, FLORIDA.

TYPEWRITER ATTACHMENT.

Application filed October 28, 1919.

To all whom it may concern Be it known that I, HARRY N. DICKSON, a citizen of the United States, residing at Orlando, in the county of Orange, State of Florida, have invented certain new and useful Improvements in Typewriter Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertams to make and use the same.

This invention relates to typewriting machines and more particularly to sheet guards, for the same, the particular purpose of the device being to keep the paper or work sheets, especially when manifolding, from being raised and blown or tumbled over the front of the machine to interfere with the vision of the operator, or being rewound on the platen or tangled with the type-bars and torn or wrinkled.

This invention is designed to overcome the above difiiculties due to the paper being turned or blown to the front of the machine by the wind, by an electric fan or by an air blast from other sources; and embodies a guard which can be attached to different makes of machines, and in particular to the Remington typewriter, and is so constructed as to rest just behind the front bar of the carriage when not in use and in such a way as not to interfere in any way with the working of the carriage as well as to permit the proper feeding of the paper or work sheets when the machine is being used.

lVith the above objects and others in view as will appear as the specification proceeds, the invention comprises certain novel combinations and arrangements of parts as will be hereinafter more particularly pointed out and claimed.

Reference is had to the accompanying drawings forming a part of this application, wherein like characters designate corresponding parts throughout the several views, in which Figure 1 is a plan view showing my improved guard applied to a typewriting machine,

Fig. 2 is a perspective view of the device when not in use,

Fig. 3 is a sectional view of the device in use.

Referring to the drawings in detail, the frame of the machine is indicated 10 hav- Specification of Letters Patent.

ing the carriage 11, paper table 12 and platen 13. The guard is attached to either side of the carriage frame by set screws as shown at 1d and comprises a pair of L- shaped or angular arms 15 pivotally supported to be swung forwardly when not in use so that the front portion of the guard rests just behind the carriage but does not touch it or in any way interfere with the working of the carriage. The guard is yoke or U-shaped.

This front piece comprises a rod 16 connecting or integral with the extremities of the arms 15, said rod being of square cross section and provided with slots 17 for receiving therein uprights 18 equidistantly spaced from the ends of the rod and also spaced from each other. These uprights are pivotally mounted in the slots to swing outwardly into operative position by rearward pivotal movement of the arms 15, said uprights can be raised and are provided with ball terminals or enlargements 19 so as to prevent tearing of the paper. In order to hold the device in position when in use or at rest, notched segments 20 are provided for engagement by a lever 21 mounted on one of the bearings of the trunnions 22 of the arms 15, the lever thus providing means to move the device into and out of operative position and to hold the same in adjusted position. It will thus be seen that the paper can be fed into the machine in the ordinary way and when engaged by the guard disposed thereover, the paper will be effectively prevented from being raised or tumbled over the front of the machine in such a manner as to obscure the operators view of the writing line, tangled, torn, or folded, especially when a breeze from an open window or an electric fan strikes the paper or work sheets. Also, the device is out of the way when not needed for use.

It should be noted that the outwardly directed portions of the arms 15 are received in bearings 23 at the sides of the carriage, there being disposed two screws at each side of the frame of the carriage to hold the plates carrying said bearing. The left hand plate also carries the projection 21 adjacent the socket or bearing 23 in order that the notched segment 20 will properly engage therewith, whereby to hold the device in an operative or inoperative position. Also, it will be noted that the arms overlie the platen, the U-shaped or yoke member thus provided being designed to swing forwardly or rearwardly of the platen and over the same. To permit this swinging and also to permit the attachment at the places stated, there is provided a bend 25 in the right hand arm in order not to interfere with the spacing lever 26. The notched segment on the right hand side is also intended to catch on a projection 27 in order to support the guard when not in use at the inside of the carriage frame, whereas the left hand notched segment also holds the device in position of use.

In connection with the uprights 18, it should be noted that the slots 17 extend entirely through the connecting portion or front piece of the guard constituted by the rod 16 and pivotally mounted as shown at 28. The uprights are also designed to be seated in longitudinal grooves 29 with their terminals 19 projecting from the ends of the U-shaped member or yoke, so that when the uprights are raised, the end portions 30 thereof will be engaged by springs 31 and thereby be held against movement when op erative to engage the paper in the manner and for the purposes specified. The uprights are held in folded relation by spring catches 32 mounted at the ends of the guard proper produced by the U-shaped member or yoke adjacent to the headed terminals 19 which project outwardly therefrom.

What is claimed is:

l. The combination with a typewriting machine having the usual carriage, paper table and platen; of a paper guard comprising a yoke pivotally mounted and adapted to be swung forwardly within the carriage of the machine or rearwardly over the paper passing around the platen, and foldable uprights carried thereby to engage the paper.

2. The combination with the carriage frame of a typewriter, and a platen carried thereby; of a guard comprisin a yoke pivotally supported at the sides of the carriage and having one of its arms upbent to accommodate the usual spacing lever, means for limiting the movements of the yoke in one direction, means for holding the same in an operative position, uprights pivoted to the cross rod of the yoke and arranged to extend at right angles thereto or to be folded into alinement therewith, springs on the rod engaging said uprights to hold them distended and catches on the rod to hold the uprights folded.

3. A guard attachment for a typewriting machine having the usual frame, carriage, paper table and platen, comprising arms pivoted to the carriage for movement behind the same when not in use and having a cross rod and uprights pivoted to said rod and having terminal enlargements, as and for the purposes specified.

4. The combination with the carriage of a typewriting machine having a platen and paper table, of arms pivoted to the sides of the carriage, a rod connecting said arms, uprights pivoted to the rod and adapted to be set adjacent or at right angles thereto and means to hold the connected arms in operative or inoperative position.

5. The combination with the carriage frame of a typewriter and a platen carried thereby; of a guard comprising a yoke pivotally supported at the sides of the car riage and arranged to accommodate the usual spacing lever, means for limiting the movements of the yoke in one direction. means for holding the same in an operative position, uprights pivotally carried by the connecting member of the yoke and arranged to extend at right angles thereto or in alinement therewith, means for holding the uprights at right angles to the connecting portion, and means for holding said uprights in alinement.

In testimony whereof, I affix my signature in the presence of two witnesses.

HARRY N. DICKSON.
